Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to an interference reporting method, apparatus, and storage medium. Background Technology

[0002] In current commercial network scenarios, numerous co-channel interference scenarios exist. Initial site planning could mitigate the impact of co-channel interference. However, with the introduction of macro-micro co-channel scenarios and shared networks, interference between co-channel stations can no longer be avoided through site planning. Existing significant co-channel interference includes interference from macro stations to micro stations and interference from other devices in shared networks. This interference can be categorized into fixed interference, semi-dynamic interference, and dynamic interference. For example, Single-Side Band (SSB) interference is fixed interference, Channel State Information Reference Signal (CSI-RS) interference is semi-dynamic interference, and service scheduling is dynamic interference. Interference caused by fixed configurations can be reduced through unified or interactive configuration. However, for semi-dynamic configuration parameters and dynamic scheduling data, the interference level can only be obtained through terminal measurement, and there is a lack of interactive information.

[0003] While existing interference feedback can reflect partial bandwidth interference through subband channel quality indicators (CQI), some interference is full-bandwidth interference, rendering subband feedback useless. Some interference is subband interference, but only affects a portion of the subcarriers or symbols; silencing the entire bandwidth or time slot data transmission would result in excessive overhead.

[0105] The present invention will be further described in detail below with reference to the embodiments, and the relevant technologies will be described first.

[0106] Existing channel feedback includes at least one of the following: Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Channel State Information-Reference Signal Resource Indicator (CRI), Synchronization Signal Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), Layer 1-Reference Signal Received Power (L1-RSRP), and Layer 1-Signal to Interference Plus Noise Ratio (L1-SINR).

[0107] The aforementioned channel feedbacks respectively reflect: channel quality, channel coding method, SSB indication, layer number indication, rank indication, layer-1 RSRP, and layer-1 SINR reporting.

[0108] As mentioned above, existing interference feedback can reflect partial bandwidth interference through subband CQI feedback. However, some interference is full bandwidth interference, making subband feedback useless. Some interference is subband interference, but only some subcarrier or symbol interference; silencing the entire bandwidth or time slot data transmission would result in excessive overhead.

[0109] Based on this, the method provided in this embodiment of the invention involves a terminal determining interference feedback; the interference feedback is at least used to indicate whether the downlink signal received by the terminal is interfered with; the interference feedback is sent to a network device; correspondingly, the network device receives the interference feedback from the terminal; the interference feedback is at least used to indicate whether the downlink signal received by the terminal is interfered with.

[0110] The present invention will be further described in detail below with reference to the embodiments.

[0111] Figure 1 This is a flowchart illustrating an interference reporting method provided in an embodiment of the present invention; as shown below. Figure 1 As shown, this is applied to a terminal, also known as user equipment (UE) or mobile device, which can be a handheld device or in-vehicle device with wireless connectivity; such as mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices (e.g., smartwatches, smart bracelets, pedometers), etc. The method includes:

[0112] Step 101: Determine interference feedback; the interference feedback is at least used to indicate whether the downlink signal received by the terminal is interfered with;

[0113] Step 102: Send the interference feedback to the network device.

[0114] In one embodiment, the granularity corresponding to the interference feedback includes at least one of the following: symbol, subcarrier, and resource element (RE).

[0115] For interference feedback of different granularities, different channel state information interference measurement (CSI-IM) modes are configured.

[0116] In one embodiment, the feedback mode of the interference feedback includes at least one of the following:

[0117] Channel state information includes CSI-RS resource indicator (CRI), Rank Indicator (RI), Feedback method (I1), and whether it is under interference or the level of interference (Int).

[0118] CRI, RI, I1, Channel Quality Indicator (CQI), Int;

[0119] CRI, RI, CQI, Int.

[0120] Specifically, the feedback quantity within the Channel State Information (CSI) feedback configuration information (CSI-ReportConfig) can include at least one of the following feedback modes:

[0121] CRI, RI, precoding matrix indicator (PMI), CQI; the format can be: CRI-RI-PMI-CQI;

[0122] CRI, RI, I1; the format can be: CRI-RI-I1;

[0123] CRI, RI, I1, CQI; the format can be: CRI-RI-I1-CQI;

[0124] CRI, RI, CQI; the format can be: CRI-RI-CQI;

[0125] CRI, RSRP; the format can be: CRI-RSRP;

[0126] SSB, Index, RSRP; the format can be: SSB-Index-RSRP;

[0127] CRI, RI, LI, PMI, CQI; the format can be: CRI-RI-LI-PMI-CQI;

[0128] You can add a new variable (reportQuantity) to reflect interference, i.e., interference feedback, such as at least one of the following for reporting interference:

[0129] CRI, RI, I1, Int; the format can be: CRI-RI-I1-Int;

[0130] CRI, RI, I1, CQI, Int; the format can be: CRI-RI-I1-CQI-Int;

[0131] CRI, RI, CQI, Int; the format can be: CRI-RI-CQI-Int.

[0132] The terminal can use the newly added variables for responding to interference to report the downlink interference level.

[0133] The determination of CRI-RI-I1-Int, CRI-RI-I1-CQI-Int, and CRI-RI-CQI-Int should be based on the feedback CRI.

[0134] In one embodiment, sending the interference feedback to the network device includes at least one of the following:

[0135] Interference feedback corresponding to RE granularity is generated and sent to the network device based on the interference indication of different resources in the CSI-IM mode corresponding to the RE granularity; the interference feedback includes: interference indication of at least one resource in the CSI-IM mode corresponding to the RE granularity;

[0136] Corresponding to the interference feedback at the symbol granularity or subcarrier granularity, based on the configuration of the symbol or subcarrier, the interference indication of at least one resource within the CSI-IM model corresponding to the symbol granularity or subcarrier granularity is determined and sent to the network device; or, based on the configuration of the symbol or subcarrier, the interference indication of at least one resource within the CSI-IM model corresponding to the symbol granularity or subcarrier granularity is determined, the determined interference indications of the at least one resource are sequentially concatenated to generate interference feedback and sent to the network device.

[0137] Specifically, different CSI-IM modes are configured for interference feedback at different granularities, such as symbol, subcarrier level, and RE level, and the terminal measures the interference of each set of CSI-IM resources.

[0138] Configured for interference feedback based on RE granularity, and due to the large number of feedback REs and the large amount of feedback information, a new CSI-IM mode is added. A CSI-IM mode can include multiple resources, and feedback is given on whether each resource is interfered with. The interference indication can be converted into a level using a bitmap. For example, if a CSI-IM mode includes 4 resources and the interference is 0110, then it will be reported as 6 through CSI. This can meet the interference measurement and one-time reporting of 36 resources. The reporting overhead per terminal is reduced from 36 PRBs to 1 PRB, and the overhead is reduced by 98% while meeting the measurement accuracy.

[0139] Configuring interference based on symbols or subcarriers requires distinguishing between symbol and subcarrier configurations. This can be done by reporting resources independently or by cascading reports in the order of resource configuration. Similarly, for RE-based granular reporting, bitmaps can be converted to hierarchical reports, and the base station can receive the reports and convert them back to bitmaps to obtain the corresponding location of the interference.

[0140] Wherein, corresponding to the symbol granularity, the interference indications of the at least one resource are cascaded according to the order of the symbols and the magnitude of their frequencies;

[0141] Corresponding to the subcarrier granularity, the interference indication of the at least one resource is cascaded according to the order of the subcarriers.

[0142] Specifically, the interference indication can start with the smallest symbol and subcarrier, then increase with the number of symbols, and then with the number of frequencies.

[0143] In one embodiment, the interference feedback is represented using a bitmap;

[0144] The characters included in the bitmap are used to indicate the level of interference or whether interference has occurred.

[0145] For example, a bitmap can contain characters that are 0 or 1. Using 0 or 1 can indicate whether there is interference. 0 indicates no interference and 1 indicates interference. Using 0 or 1 to indicate whether there is interference can reduce feedback overhead.

[0146] The bitmap can also include different numbers, which represent different levels of interference; for example, 0104, where 0 means no interference, 1 means interference level 1, and 4 means interference level 4.

[0147] Specifically, the interference indicators of each resource in the interference feedback can be arranged according to different resources under the same model, and converted into a level report using a bitmap, such as "0104" above.

[0148] The interference indications for each resource in the interference feedback can be reported independently according to different resource configurations, using bitmap method; such as 0 / 1 as mentioned above;

[0149] Interference indications for each resource in the interference feedback can be cascaded and reported according to different resource configurations, and converted into hierarchical reporting using bitmaps. The cascading method can be arranged in the following order: starting from the first symbol, the first subcarrier, and then increasing by symbol and frequency.

[0150] In practical applications, a full feedback method can be adopted, which means that all interference indications measured each time are reported.

[0151] Based on this, in one embodiment, the transmission of interference feedback includes:

[0152] Send a disturbance indication for at least one resource;

[0153] The interference indication for each of the at least one resources indicates whether the corresponding resource is interfered with or the level of interference.

[0154] Specifically, at least one set of resources is configured, and the configured resources include at least: channel state information interference measurement (CSI-IM) resources and channel state information reference signal (CSI-RS) resources corresponding to the CSI-IM resources; the CSI-RS resources in each of the at least one set of resources point to the same time-frequency resources;

[0155] The feedback mode of the interference feedback includes at least one of the following:

[0156] CRI, RI, I1, CQI; the format can be: CRI-RI-I1-CQI;

[0157] CRI, RI, CQI; the format can be: CRI-RI-CQI.

[0158] The CQI includes: Channel State Information (CSI) of the corresponding resource, specifically interference indication.

[0159] For example, at least one set of resources (maximum 24 sets) can be configured. The at least one set of resources can be configured by the base station and then informed to the terminal. The resources are CSI (CSI for interference) resources, specifically including CSI-IM and the corresponding CSI-RS resources. The CSI-RS resources point to the same time-frequency resources.

[0160] Correspondingly, 24 sets of CRI-RI-I1-CQI or CRI-RI-CQI are fed back, occupying 24 physical uplink control channel (PUCCH) physical resource blocks (PRB). This scheme can accurately feed back the interference indication of each resource, but the overhead of each user CSI cycle of 20ms may be greater than 0.5%.

[0161] In practical applications, this can be achieved through incremental feedback.

[0162] Based on this, in one embodiment, the transmission of interference feedback includes:

[0163] Send a disturbance indication for at least one resource;

[0164] Wherein, the interference indication of the first resource in the at least one resource indicates whether the first resource is interfered with or the level of interference;

[0165] The interference indications for the resources other than the first resource in the at least one resource represent the difference between the interference indications of the corresponding other resources and the first resource.

[0166] The first resource can be the first resource that needs to be fed back among the at least one resources; the other resources are the resources after the first resource.

[0167] Here, a full-bandwidth Channel Quality Indicator (CQI) can be sent; the CQI includes the CSI of the corresponding resource, specifically the Interference Indicator.

[0168] The feedback mode of the interference feedback includes at least one of the following:

[0169] CRI, RI, I1, CQI; the format can be: CRI-RI-I1-CQI;

[0170] CRI, RI, CQI; the format can be: CRI-RI-CQI.

[0171] For example, a specific interference-format indicator can be defined, and incremental feedback can be configured, i.e., 24 CSI feedbacks, referencing the baseline CQI, with feedback increments, and an overhead of 12 PUCCH PRBs. The overhead per user CSI cycle is greater than 0.2% in 20ms.

[0172] The following example illustrates the difference between the full feedback method and the incremental feedback method described above.

[0173] Suppose that after detection, the terminal determines the interference indications of five resources as follows: 1, 1, 3, 3, 3 (the above data can represent the interference level);

[0174] If the full feedback method is used, the feedback interference indication is: 1, 2, 3, 3, 3;

[0175] If incremental feedback is used, the feedback interference indication is: 1, 0, 2, 2, 2.

[0176] In one embodiment, determining the interference feedback includes:

[0177] The reference signal received power (RSRP) and / or the reference signal to interference plus noise ratio (SINR) of the downlink signal are detected as the detection values.

[0178] Based on the interference threshold and the detected value of the downlink signal, determine whether at least one resource of the terminal is interfered with; or, based on the interference threshold and the detected value of the downlink signal, determine the interference level of at least one resource of the terminal.

[0179] The interference threshold includes at least: a reference RSRP value and a reference SINR value from the base station.

[0180] Based on the interference threshold, the terminal can determine whether it is being interfered with based on its own measurement results, enabling the terminal to perform self-testing and report.

[0181] Here, the interference threshold can be a threshold value for different resources, used to determine whether the corresponding resource is interfered with;

[0182] The interference threshold can also be multiple threshold values ​​for different resources, which can be used to determine whether the corresponding resource is interfered with, and also to determine the interference level based on different threshold values.

[0183] For example, after the base station sends an interference threshold (such as a reference RSRP value) to the terminal, the terminal detects the RSRP and determines that the detected RSRP exceeds this reference RSRP value, and considers the corresponding resource to be interfered with.

[0184] Figure 2 This is a flowchart illustrating an interference reporting method provided in an embodiment of the present invention; as shown below. Figure 2 As shown, this method is applied to network equipment, which can be base stations, relay stations, or access points, etc. The base station can be a base transceiver station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) network, an NB (NodeB) in Wideband Code Division Multiple Access (WCDMA), an eNB or eNodeB (evolutionary NodeB) in LTE, a gNB in ​​a 5G network, or a network device in a future PLMN network, etc. The method includes:

[0185] Step 201: Receive interference feedback from the terminal; the interference feedback is at least used to indicate whether the downlink signal received by the terminal is interfered with.

[0186] Network devices can adjust downlink data based on received interference feedback to improve network performance.

[0187] In one embodiment, the granularity corresponding to the interference feedback includes at least one of the following: symbol, subcarrier, RE;

[0195] The interference feedback corresponds to the symbol granularity or subcarrier granularity. It is an interference indication sent by the receiving terminal, which is determined based on the symbol or subcarrier configuration, for at least one resource in the CSI-IM model corresponding to the symbol granularity or subcarrier granularity. Alternatively, it is an interference feedback generated by sequentially concatenating the interference indications of at least one resource in the CSI-IM model corresponding to the symbol granularity or subcarrier granularity after the receiving terminal determines the interference indication based on the symbol or subcarrier configuration.

[0201] The receiving terminal sends an interference indication for at least one resource;

[0202] The interference indication for each of the at least one resources indicates whether the corresponding resource is interfered with or the level of interference.

[0203] In one embodiment, receiving interference feedback from the terminal includes:

[0204] The receiving terminal sends an interference indication for at least one resource;

[0205] Wherein, the interference indication of the first resource in the at least one resource indicates whether the first resource is interfered with or the level of interference;

[0206] The interference indications for the resources other than the first resource in the at least one resource represent the difference between the interference indications of the corresponding other resources and the first resource.

[0207] Information regarding interference feedback and the corresponding methods for transmitting interference feedback has been provided in [the relevant documentation / documentation]. Figure 1The method is explained in the diagram and will not be repeated here.

[0208] In one embodiment, the method further includes: sending an interference threshold to the terminal; the interference threshold includes at least one of the following: a reference RSRP value and a reference SINR value.

[0209] In one embodiment, the method further includes: the network device scheduling downlink data based on interference feedback to improve network performance.

[0210] To reduce the impact of co-channel network interference, a channel interference measurement and reporting method is proposed, specifically through... Figure 1 and Figure 2 The method shown enables downlink interference reporting in co-frequency networking.

[0211] The embodiments of the present invention specifically provide three methods. One method is to use the CSI method to report the full amount, which is easy to implement but has a large overhead and insufficient resource capacity. Another method is to use the incremental CSI method, which is easy to implement and can reduce the overhead, but the resource capacity is still insufficient. The third method is to report whether there is interference at the same time, and to use the bitmap to level conversion, which greatly reduces the reporting overhead and measurement overhead.

[0212] The following provides further explanation of the three methods mentioned above.

[0213] One approach employs a full CSI feedback method, specifically configurable with up to 24 CSI (CSI for interference) resources. These include CSI-IM and corresponding CSI-RS resources, with the CSI-RS resources pointing to the same time-frequency resource. Feedback is provided through 24 CRI-RI-i1-CQI or CRI-RI-CQI sets, occupying 24 PUCCH PRBs, resulting in a 20ms CSI cycle overhead of greater than 0.5% per user.

[0214] Another approach uses incremental feedback. Specifically, incremental feedback can be configured by defining an interference-format indicator (interference-FormatIndicator), resulting in 24 CSI interference feedbacks referenced to the baseline CQI. This scheme incurs an overhead of 12 PUCCH PRBs, with a 20ms CSI cycle overhead exceeding 0.2% per user.

[0215] Another method for interference measurement reporting is through newly added interference feedback. Specifically, the feedback quantity (reportQuantity) in the current feedback configuration (CSI-ReportConfig) includes the following combinations: CRI-RI-PMI-CQI, CRI-RI-I1, CRI-RI-I1-CQI, CRI-RI-CQI, CRI-RSRP, SSB-Index-RSRP, and CRI-RI-LI-PMI-CQI. In this embodiment of the invention, it is necessary to add a variable (reportQuantity) that reflects interference, such as CRI-RI-I1-Int, CRI-RI-I1-CQI-Int, and / or CRI-RI-CQI-Int, for reporting interference.

[0216] In the above scheme, an interference threshold can be defined and sent to the terminal via RRC reconfiguration. If the terminal measures RSRP and determines that it is higher than the interference threshold, it is considered to have interference; otherwise, it is considered to have no interference.

[0217] Figure 3 This invention provides a schematic diagram of a format for Full Information Feedback (CSI) and Incremental Information Feedback (CSI); wherein, (a) is the full information feedback format, which provides interference indications for all resources each time;

[0218] (b) is incremental information feedback, which refers to supplementing the feedback with the indication of the change or addition of interference based on the previous feedback; in the figure, the form of CSIa / b (such as CSI11 / 12, CSI23 / 24) means that each bit can carry the information of both CSIa and CSIb.

[0219] The method provided in this invention adds an interference feedback format to the channel feedback information, and reports the downlink interference level by measuring the terminal. The interference level feedback can use existing full-information feedback or incremental information feedback. Incremental feedback requires a new interference-format indicator (CQI), using full-bandwidth CQI as a benchmark. Incremental feedback reduces feedback overhead. Furthermore, for the interference feedback method that adds a new interference variable, a 0 / 1 response can be used to indicate whether interference exists, instead of the previous CQI, further reducing feedback overhead.
